In vitro shear bond strength of the Amalgambond Plus system.
The bonding of composite resins to dentine by means of dentine bonding agents is common practice. Although amalgam has been used for many years, no attempt had been made to bond it chemically to tooth structure. Amalgambond Plus (ABP) was developed to bond amalgam (as well as composite) to various substrates. The purpose of this study was to evaluate the ABP system for its ability to bond amalgam, as well as composite, to dentine, and also to assess the strength of the product when bonding composite to set amalgam. The following values (MPa) were obtained for the different ABP variations: Amalgam to Dentine (with HPA): 5.20; Amalgam to Dentine (without HPA): 3.26; Composite to Dentine (without HPA): 17.57; Composite to Amalgam (without HPA): 12.00. It can be concluded that Amalgambond Plus gives varying bond strengths to different substrates, with the highest value obtained when used to bond Composite to Dentine.
